UDP-D-galactose + quercetin
UDP + quercetin 3-O-beta-D-galactoside
-
role in pollen germination
quercetin 3-O-beta-D-galactoside induces pollen germination via the reverse activity
-
r
UDP-galactose + quercetin
UDP + quercetin 3-O-beta-D-galactoside
-
role in pollen germination, F3GalTase is a gametophyte-specific enzyme, that controls the accumulation of glycosylated flavonols in pollen
endogenous product in pollen, which stimulates pollen germination
-
r
UDP-galactose + flavonol
UDP + flavonol 3-O-beta-D-galactoside
-
F3GalTase controls the formation of glycosylated flavonols in pollen, enzyme also catalzes the reverse reaction, i.e the production of flavonol aglycone from the galactoside and UDP, and has therefore the potential to control the level of the bioactive flavonol species and as a result, pollen germination, the direction of the reaction could be controlled in vivo by localized hydronium ion changes, control mechanisms of the reversible reaction

-
r
UDP-galactose + flavonol
UDP + flavonol 3-O-beta-D-galactoside
F3GalTase controls the formation of a pollen-specific class of glycosylated flavonols, role in flavonol-induced pollen germination, F3GalTase is expressed exclusively in the male gametophyte, where it modifies a molecule required for functional pollen
